To all whom it may concern:

Be it known that I, ISAAC D. STINE, a citizen of the United States, residing at Decatur, inthe county of Macon and State of Illinois, have invented certain new andu'seful Anchor-Sockets for Screws, of which the following is aspecification. I

This invention relates to certain improvements in means for securing screws in wood,

and more particularly to -a metallic socket forming whatnlight be termed'a metal screw hole; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawmgs showing what I now consider my preferred embodiment. V

An object of the invention, is to produce a new article of manufacture consisting of a pointed metal bushing orpin having a longitudinal screw threaded socket or bore and adapted to be'driven into a' wooden article or structure at the point where a screw is to be located to form a socket or screw threaded hole for the reception of such screw and whereby the screw can be repeatedly removed and reinserted without injury to the wood work or screw hole.

The invention consists ina new article of manufacture, to wit-;a pointed metal pin formed to be driven into wood or the like, and having a longitudinal internal screw threaded socket to form a screw hole for the. reception of a screw. Referring to the accompanying mgs;Figure .1, shows a jamb and a stop in section, the screw securing socket of my invention shown in longitudinal section and secured in the jamb, and receiving a screw passed through the stop and shown in elevationi Fig.- 2, is L3. detail elevation of the screw securing socket of'Fig, 1. Fig; 3, is-a view similar to Fig. 1, but showing a modified formation of screw securing socket.

The article of my invention consists of an elongated metal pin 1, formed in one piece of metal, and having a closed or solid pointed end '10, for driving into wood or other material in which a screw 2, is to be secured. This pin is formed with a longi tudinal socketorv bore 11, having a closed inner end and opening through the outer end or head of the pin. This socket is of a length and diameter to snu ly receive the desired length of the threaded portion {of the screw and is internally and longi- Specification of Letters Patent.

tudinally threaded to correspond to the gage and character of the thread of the screw and to properly hold'the screw. The pin is of such external diameter as to provide suflicient strength and body to properly support the screw and sustain the strain and stress incidental tobeing forced into the wood by driving or hammering. The pin is usually approximately cylindrical in form, but is exteriorly formed for anchoring inthe wood.

For instance, the pin can be formed with external annular anchoring grooves 12, see F ig. 3, into which the wood (compressed by the entrance of the pin thereinto) can expand to firmly and rigidly lock or anchor the pin in the wood. However, I prefer, to form the pin with exterior annular anchor ing depressions about as shown in the re maining figures of the drawings wherein the pin is externally formed with taperingportions 13, contracting toward the point of the pin and terminating at outwardly facing annular shoulders 14. To prevent injury to the internal screw thread by the impact of the hammer orother implement on the head or outer'end of the pin in driving, I ream out or flare the outer end of the bore or socket of the pin, see'15, so that the internal screw' thread begins at the inner end of the flared or enlarged portion ofthe bore and hence the thread. will not be injured should the outer. end or head of the pin be burred or slightly flattened by driving. r

This article is particularly intended for use in connection with the'screws by which window and door stops are secured to jambs driven into the jamb, frame or other part,

after such jamb has had the point where the pm is -to be located, marked thereon by inserting the screw in proper .position in the stop and starting the screw point into the j amb. The pin is then driven .into the j amb at the indentation thus marked by the screw point. Where this socket is employed, the screw can be removed-and reapplied as often as required-without marring the wood work or destroying the holding'qualities of the screw hole.

What I claim is;

A screw securing socket adapted to be driven into wood and consisting of a pin having a solid pointed inner end and a longi- 6 tudinally threaded screw receiving bore open at the outer hammer blow sustaining end of anchoring depressions, substantially as de* 10 scribed.
